Be itknown that I, STEPLING W. VARNER, a `citizen of the United States,and a resident of Cranford, Union County, and State of New Jerseyrhaveinvented certain new and useful Improvements in PerforatedMusicDuplicating Machines, of which the following is a specification,reference be-l ing had to the accompanying drawings, forming a partthereof. y

y invention relates topneuinatic duplicators for perforated music rollsparticularlyof the type inv which a master roll is carried over atracker bar and the mechanism connected thereto rapidly fully reproducesthe original or master roll in a plurality of copies.

Ain,` object of the invention isto provide a compact, reliable andefficacious apparatus for faithfully and correctly duplicating theoriginal master roll in` one or more copies. A, further Objectis to`provide quick act-y ing, automatic means for the purpose de scribed.

Other objects relate to the` simplicity of the mechanism, durabilityofconstruction and responsiveness master sheet. y y y W'ith theforegoin'gand other objects in view, which will become apparent as thedescription proceeds, my invention residesfv be' duplicated, hereinaftercalled a. master ,in the combination and arrangement of parts and in thedetails of construction, with dueregard for mechanical equivalents,described in the specification, illustrated in the drawings, andparticularly pointed out in the appended claims, it being understood ythat l do not limit myself to the `precise embodiment of theinventionherein disclosed and changes can be in ade within the scope of what isclaimed without departing from the spirit of the invention. Iv thereforeintend no limitations other than those imposed by the appended claims.

Each pneumatic 30 communicates by a 6) with a valve chamber 28 in'whicha valve 27 controls a passage 26 to the atmos )here and a passage 25 toa suction chamber 24, exhausted through pipe 40, each valve 27 beingoperatively supported on a pouch 23. These pouches 23 septhe ducts Ableed hole 22 c, previously mentioned.

duct c with (Figs. 6 and 8) connects each the suction chamber 241.-.

Both chambers b and 24 are normally suction or vacuum chambers,communicating bv pipes 39, L10 (Fig. 1), respectively, with pipes 37, 38leading to a main suction pipe (Fig. 5) is open to the atmosphere; andwhen the valves 16, 16, are raised., as shown in the upper part of Fig.5, ducts a likewise communicate with the atmosphere through the passagescontrolled by the valves 35, 35a. ,p

It will be understood that Leach double duct 9, 9b of thetracker bar isconnected by valve devices simso that each double tracker-ductcontrolsthe vibratory operation of a single punch operating pneumatic 30 asfollows:

Tn Fig. 13 it is assumed that a single perforation in the master sheethas reached in the punchy ,to raise said pouch. In other words,

foration of the master the position vwhere only duct 9 of one of thedouble ducts is uncovered. This permits air to enter through tube 20 tothe duct 18 (Fig. 5) the yvalves 16, 16a, lbeing vnormallyin thelowerlposition as shown in the lower valve chest of Fig. 5. This normalposition lof the valves is maintained when the tracker bar ducts areco-vered by reason of the ducts 18, 18a being evacuated through thebleeds and bleedpassages 21, whereupon the atmospheric pressure on thevalves forces them downwardinto the position shown in the lower valvechest. i

Y By the admission of air to the duct 18 as ,y by uncovering'the duct9a,`the valve 16 is raised to the position shown in the top chest ofFig. 5, the atmospheric pressure under the diaphragm 17 overcoming thereduced pressure in the suction chamber b above the diaphragm. f

The aforesaid raising of the valve 16admits atmospheric air to the ducta (Fig. 5) past the valve 35, a portion 34; of said valve 16 cutting offcommunication of. the duct a with the suction chamber b. However, thisair is insufficient to raise the pouch 23 and valve 27 (Figli) becausethe arrangement is such that the air admitted by the valve 35 is not sogreatv in amountbut that it can be and is exhausted into -the chamber bpast the valve 34e (which under the supposed conditions is in itslowered position) without, therefore, being able to affect the eX- haustcondition under the pouch 23 (Fig. 6)

, y in Fig. 6 with its punch operating. pneumatic 30 on atmosphere andtherefore out of operation.

W'hen, however, said assumed single perf i sheet has travelled furtherto the position shown in Fig. 14, it uncovers also the second (9") ofthe tracker ducts, iwhereupon the air admitted through the duct 18a(Fig. raises the other pouch 17a and the second valve 169,35a and closes110 34?. At this time the exhaustchamber t is completely cut off fromthe duct a, tube 15 and duct c `under the related pouch-23 (Fig. 6) gand instead only atmospheric air is now admitted under said pouch by wayof the two open valves 35i-35% The result is that vsaid pouch isimmediately raised and in turn lifts the v-alve 27.

This lifted valve 27 thereupon seals the i, atmospheric port and opens aport 25 con- 120 necting the related punch-operating wpneumatic 30 withthe suction chamber 24. Thereupon the movable board 11 of said pneumaticis immediately depressed and drives v. the related punch 33 up throughthe blank 12: sheet or sheets 4: to cut 'a single perforation thereincorresponding to the assumed single perforation in the master sheet,

This movement of the movable board 11 i. i depresses the rod 12 attachedthereto (Figs. 130

the rod 12, th

` tion shown in` 'into itself the atmospheric air which is bethe openvalve 35?L 6 and 9), said rod adjustably supporting a` slide valve 13.Through the slide valve 13 is a passage 32 registering between the tubeY 15 and the duct c when the pneumatic is in normal open position. Ondepression of e motion is communicated to slide valve 13 and the passage32 is removed from `registering position untilthe duct c is completelyshut off from the tube 15 by the solid portion of the valve 13.

Immediately the air in duct c which held up the pouch 23 and valve 27 isexhausted through the bleed `and bleedspassage 22 (Fig. 6) into thesuction chamber 24 and a l relative vacuum is established below' thediaphragm 23y whereupon the valve 27 is again depresse the `suctionpassage 25'` closed and atmospheric air is again admitted throughpassage 26 to the interior of the pneumatic 30.` This together with theaction of the resilient member 49 results in said pneumatic openingagain to the posi- 6, the valve passage 32 again registering between thegiven pipe 15 and ducto. l c

`This withdraws the punch which does not again operate because meanwhilethe assumed single perforation in the master sheet lOhas passed beyondduct 9a (lFig. `1F) and said duct is closed, only the cuct 9b beingopen. The result is thatthe air in tube 2O and duct 18 is quicklyexhausted through its bleed 21 5) thepouch 17 drops, and the valve y35closes 4again and opens valve 34. The suction chamber now draws ingadmitted to the duct a (Fig. 5) by and further immediately exhausts thepipe 15.` In other words. there now no atmospheric air on the pipe 15necessary to operate the pouch 23 (Fig. 6) and, therefore, saidpouchremains down and so keeps its punch-pneumatic `3() out of operation. f i

From the foregoing it willbe seen that mydescribed machine produces thedesirable result that Va single perforation in the master` sheetautomatically reproduces itself as a single perforation in. the copies,the single punching operation taking place at the moment when both ofthe tracker ducts 9a and 9b are opened as in Fig. 14 by the masterperforation; and not occurring before that as when only 9a is open as inFig. 13,` nor later as when only 9b is open as in Fig.15. `r

ln the event of a slot in the master sheet (as distinguished from asingle perforation) passing over any ofthe double vducts 9a, 9", thefirst effect is to depress the given bellows boardrll and punch as inthe case `of aysingle perforation lalready described.

The `passage through the related valve 13 (Figo) is'f'closed, therelated duct c is evacuated as before explained and its valve is againlifted and blank sheets l4, val

spaced equally,y

This cycle continues, the givenpunch rapidly vibrating so long as the correspond'ng tracker ducts 9a,9b, are open to air through the supposed slot in the master'sheet. Thisproduces a plubar duct-s being-still uncov- 1 `ered by the slot in themaster sheet and :the valves 35,
